Why do some phone chargers make weird buzzing noises?
Mostly it is because of electricity running through it and it’s wire coils in it’s step down transformers and rectifiers . All electronics make noise just most don’t make them loud enough to hear with an unaided ear . Sometimes it is because of the wavelength they produce sound at . They do make noise none the less . The chargers that do make noise if normal may not have anything to deaden the sound radiating from them and sometimes if not normal it is because of electrical leakage shorting to ground . If a otherwise quiet charger starts to make a sounds then discharge the charger as it may be shorting inside and possibly cause a fire .
Why do my earphones sound high-pitched?
Congratulations on using real headphones! You are experiencing poor audio compression. The highs in “Hymn For The Weekend” come from a drum machine track from the 90’s. Modern pop music is mastered and compressed into oblivion in order to sound good on a smartphone speaker. So when you listen to it on a real sound system, it still ends up sounding like an iPhone. To solve your problem, you need to do a couple of things.Delete Spotify: Spotify streams at 160 kbps, which is fine for carpool karaoke and gym workouts, but your M40’s will let you hear all that nasty low res distortion.Rip some CD’s: Find some music you like on CD from the library. This will be much higher quality than streaming or iTunesDevelop better taste in music: In the nicest way possible, you need to get away from the mainstream pop. Most of it is not mastered very well and will leave you wanting more, like an off-brand Twinkie. If you need to things to ease you into the eclectic world of HiFi tracks, I recommend you take a look at some of the more ‘hip’ options:Michael Jackson: ThrillerGorillaz: The FallDaft Punk: RAMTaylor Swift: 1989Lemme know how that goes!
Is the modern world pitched at A=440...or am I slowly going MAD?
This may sound crazy, but please bear with me. Now, recently, I've been catching a lot of buses to and fro, which is a drag, but the trips are far more bearable if I plug myself into my mp3 player and indulge in my beloved Baroque music. But I've noticed something quite disconcerting. Whenever I listen to music played at Baroque pitch (A=415) it sounds really off, kind of out of tune or something - whereas if I listen to modern performances (A=440) there's no problem whatsoever. And the other day, I added one of my favourite Lully recordings to the mp3 player, performed at French Baroque pitch (A=392) - but it sounded so disgustingly out of tune, I simply couldn't listen to it. At first, I was worried that there was something gravely wrong with my hearing...maybe all those years of playing bassoon had blown a gasket or two in my brain. But eventually I realised this phenomenon happens only when I'm on the bus, listening to my mp3 player. I've enjoyed these CDs for many years, and never noticed any problems whatsoever when listening at home on my CD player. Then it struck me that maybe the "pitches" of the bus were "clashing" with the Baroque tunings and temperaments. I don't have perfect pitch, but a reasonable sense of relative pitch - and it hit me that the constant whine of the bus engine, indicators, bell (for disembarking), etc. - all at fixed pitches - were clashing with the "Baroque pitched" recordings feeding directly into my ears - and the French Baroque recording was even more excruciating. My question is thus: is the modern world really fixed at modern pitch? And conversely, in the past, did the world (generally speaking) operate at a lower pitch? I'm sure many of you are thinking, "Poor Hafwen, the recent heatwave has totally melted her mind" - but nonetheless, I'd be very keen to hear your thoughts here. Thanks in advance! Hafwen x
What would cause a popping/crackling sound in one of my stereo speakers?
Most popping or crackling sounds in an audio system come from a bad or dirty connections. Sometimes they do come from a faulty unit or component, but in most cases it is a connection issue. Whether that connection is in the connectors, wiring, circuit board or components, or even just a bad solder joint, wherever that connection is, finding it becomes the main issue to tackle. There are some relatively simple methods that can be used to locate it.First identify which part of your audio system has the issue. The fact that it is only in one of your speakers is a huge help in identifying what might be causing the noise. If both channels had the same noise, this method would not work. You can easily identify the source by swapping the channels and seeing if the noise moves or stays on the same channel.For example, swap the channels the speakers are connected to. Does it persist on the same speaker or does transfer to the other? After swapping, if it remains with the same speaker ( other channel), then it is the speaker connections (or the speaker itself) that are problematic. If it is now on the same channel (other speaker), it is somewhere in the system, before the speaker connections. You can continue to swap different components back and forth, swapping channels and work back to where the source and component is identified.Sometimes just connecting and reconnecting the cables and components solves the problem, as the connection is improved. Good luck!One component that usually becomes noisy that way (more of a crackling sound than a popping one)is a potentiometer (also called a ‘pot’, normally volume controls, bass-treble-balance controls, etc.). These can be easily identified by rotating or sliding the controls as the case may be, and listening for the noise. These can be cleaned with the right solvents or sprays.Worst case scenario is a failed or failing component such as a transistor, capacitor, resistor, solder joint (actually solder joints are relatively easily repaired, just identifying the problematic one is the challenge!), etc.Once you have identified the part or unit in the system that is causing the noise, then it will be easier to decide how best to correct the issue (replace or repair).
Everything sounds low pitched?
Hello, Ever since I got back from my plane, everything sounds low pitch. I thought it was my earphones that I used, but I only set them to the volume that I always use. It's not so low pitch that like everyone sounds like Darth Vader, but that it is a bit noticeable. I checked and everything that I knew sounded like (my favorite songs, Skype call sound, phone sound, my YouTube intro song, etc) sounds too low pitch: 2% to be exact. (Voices are unaffected) Please help. PS: When I was using a q-tip in my left ear, it hurt. I've also had a history of wax-filled ears in the past. Could this be the cause?
Logitech G430 mic makes my voice's tone sound super low and slow?
I started streaming recently but had to stop right away because I noticed my voice didn't match how I sound like at all. At first, I thought it was an OBS issue but turns out it's my headphones mic. If anyone has ever seen the CW show, Arrow, i voice sounds like the device they use to disguise their voices so they won't expose their identities. I don't what the issue is; I have the latest update of everything: Windows 10, Logitech software, drivers, etc. I can't seem to find the solution to my problem and there aren't any forums that can help me either cause no one seems to experience the same issue as me. if anyone knows what could be the issue please tell me. I'm so desperate to just get the mic to work when streaming and recording. note that this issue only occurs when streaming or recording, never when I'm chatting with people on any chat software.
How do I remove static noise from bluetooth speakers?
Try connecting the speaker to a music source using a stereo audio cable plugged into the Line In Audio socket of the speaker and the headphone socket of a mobile phone (for example).If there is no noise, there may be a problem with the Bluetooth connection. Remove any pairing connections stored in the speaker and also the Bluetooth device (e.g. phone) (see previous answer to you with User Guide link) then re-pair with the Bluetooth source and see if it is still noisy.If it is still noisy, remove the Bluetooth connection 'stored in the speaker and try pairing with a different Bluetooth device, (ensure that the 1st Bluetooth device has the Bluetooth turned off) and see if the noise is still present.If there is noise when using both the Bluetooth and the stereo cable there is a problem within the speaker. There are a lot of things in a powered speaker which, if faulty, can produce unwanted noise and it would have to be opened so that it could be checked to see what is causing the problemYou can do these following stepsStep 1The best and most reliable method for reducing interference is to move the Bluetooth device (the smartphone, the tablet, etc.) closer to the wireless speaker. The further the distance between the device and the speaker, the more interference you are going to get.Step 2Try re-pairing the device with the speaker. Turn off the speaker, and shut off the Bluetooth on your phone or tablet for a few minutes. Turn the speaker back on and re-enable Bluetooth on your device. Finally, reconnect the two devices.Step 3If simple re-pairing doesn’t work, try to use the speaker with a different Bluetooth device. The interference/sound quality issue could be a problem with your mobile device and/or your mobile network service.Step 4Most Bluetooth speakers will give you some option to reset the factory settings. You will have to do research on your specific speaker product to do this, either by looking it up online or reading the owner’s manual.RecapNone of these steps are guaranteed to solve the interference problem you’ve been having with your Bluetooth speaker and your mobile devices. However, all have solved sound quality issues for Bluetooth speaker users at one point or another, so they’re all worth trying if you want to solve the problem.you check out these links alsohttps://www.eevblog.com/forum/beginners/bluetooth-module-noise-issue/
Why do singers in concerts or TV shows wear an earphone in one ear?
They are called as "In Ear Monitors"Monitors, are speakers which musicians and singers use to hear themselves and the band properly to be able to perform on stage. Bands generally are not able to hear themselves if it is not small venue or if they don't have monitors. Every musician has one or sometimes 2 monitors in front or next to them on a stage.Monitors can be like a speaker in front of the performer or they can be 'In Ear Monitors"Some companies make the monitors by molding the shape of your ear to make the "In-Ears" a perfect fit. In Ear Monitors are wireless which come with device(which goes to the sound console) to transmit the audio.
